Improved sediment-collector for steam-boilers



UNITED STATES PATENT OFFICE.

J. T. PRICE, OF ROCKVILLE, INDIANA.

IMPROVED SEDlMENT-COLLECTOR FOR STEFAM-BOILERS.

Specification forming part of Letters 4Patent No. 28,303, dated May 15, i860.

To @ZZ whom it may concern:

Be it known that I, J. T. PRICE, of Rockville, in the county of Parke and State of Indiana, have invented a new and Improved Sediment-Collector for Steam-Boilers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of thIs specification, in which Figures l and 2 are vertical sections, at right angles to each other, of a boiler having my improved sediment-collector applied.

Similar letters of reference indicate corresponding parts in both gures.

My invention consists in a novel system of pipes applied to a boiler, in connection with a water-heater arranged as a bridge in rear of the fire-grate, for the purpose of collecting the mineral or other sedimentary Inatter from the water and preventing its deposit in the boiler.

To enable others skilled in the art to Inake and use my invention, I will proceed to describe its construction and operation.

A is the boiler, arranged in the usual or any suitable manner in its setting B B.

L is the tire-grate, arranged below the front of the boiler, and D is the heater, which constitutes the firebridge, consisting of a drum arranged below the boiler transversely to the grate C, and immediately in rear thereof and extending right through the setting B B, so that both ends are accessible, and having a man-hole, E, in each end. This heater is connected at the top with the bottom of the boiler A by a short pipe, F, of large diameter, the said pipe having the whole area of its bottom in communication with the heater, but having no communication with the boiler.

G is a pipe, of smaller diameter than the pipe F, extending from a short distance below the bottom of the boiler down through the center of F and along the heater D to near one end thereof, having no direct communication with the heater, but connecting with the blow-off pipe Il, outside of the boiler-setting, as shown in Fig. l.

I isa short pipe, of smaller diameter than the pipe G, att-ached to the bottom of the boiler in the center of the large pipe F, and dipping down into the open upper end or mouth of the pipe G, which is of funnel shape, said pipe forming the only communication between the boiler and the heater D and pipes F G.

J is a valve in the pipe G, near the connection of the said pipe with the blow-off pipe, for opening a communication between the said pipe and heater D, near the bottoni of.-

the latter, said valve being furnished with a screwed stem, J or some equivalent means of opening it from outside of the heater.

K is the feed-pipe for supplying the boiler, connected with the bottom of the heater D, to deliver the water into the boiler through the said heater.

The operation of the apparatus is as follows: The water fed into the heater passes therefrom to the boiler, as indicated by the arrows in the two ligures, up between the pipes F and G, down between the pipes G and I, and up through I, and the pipe G is kept filled. The heater being exposed to the heat of the fire the water is boiled therein, and the steam generated therein takes the same course indicated by the arrows and rises through the body of water in the boiler. As the pipe G is somewhat cooler than theheater D, by reason of its deriving its heat only from the latter, and as all of the interior of said pipe butthe upper part is out of the feed circulation the water therein is comparatively little agitated, and hence the greater portion of the solid matter contained in the water or precipitated therein by ebullition in the heater and carried by the feed and steam circulation over the top of the pipe G is caused to subside into the said pipe, from which it may be drawn from time to time through the blow-oit` pipe by openin g the blowoff cock, the subsidence in the said pipe G being aided by the downward circulation at its mouth. A portion of the sediment will also be collected in the heater, from the bottom of which it may be blown out through the pipe G by opening the valve J and the blow-off cock.

Vtfhat I claim as my invention, and desire to secure by Letters Patent, is

The system of pipes F G I, applied to a boiler, in connection with a heater, D, the whole arranged substantially as herein described, for the purpose set forth.

J. T. PRICE.
